Garmin Nexus 43 mm Thru-Hull Speed/Temperature Transducer, Retrofit Transducer, NMEA 2000® Network Compatibility

The Garmin GST™ 43 through-hull transducer is capable of measuring not only temperature but also speed. If you already have a Nexus 43 mm transducer, you can use the GST™ 43 for retrofitting a through-hull mount. In this pack with the GST 10, the device connects directly to the NMEA 2000® network, allowing you to display the information on a compatible Garmin chartplotter or instrument display.
